I was trying to draw a PCA plot using FactoMineR (a R package). When I ran it, texts on the plots were overlapped with unknown numbers.
Here's the R code
library(FactoMineR) pca<-PCA(dta.cor, scale.unit=T) plot.PCA(pca,cex=1)
and the result plot
As you can see numbers in pink are covering sample names.
I couldn't figure it out.
Please, someone help me!!
